Generally cysts size in range from about 3-7 microns and can be reduced by fine filters however to completely remove 100% a filter pore size have to be at least 1 micron absolute with greater than 99.99% efficiency. Many filters on the market claim cysts reduction using surrogates (AC fine test dust in 0.5-3 micron size range) test standards vs. live cysts method which is tougher and more accurate test.
